New Dry Strength Program Helps Containerboard Mill Produce High Performance Grades With Deteriorating Waste Paper Qualities

GoalProduce high performance grades with deteriorating waste paper qualities.

<h6>Customer Challenge</h6> <p>A European containerboard producer was not able to produce high performance packaging grades with traditional starch-based strength additives.</p> <h6>Recommended Solution</h6> <p>Solenis evaluated the mill furnish and recommended the use of Xelorex RS1300 paper performance additive, a cationic Polyvinylamine homopolymer, added prior to the centri-screen.</p> <h6>Results Achieved</h6> <p>The mill can now consistently achieve the required specifications for high-performance packaging. SCT, CMT and burst characteristics improved by 15%. In addition, the retention aid was reduced by 50%, the fixative was eliminated, and surface size addition reduced by around 10%. Machine productivity was improved through reduction of sheet breaks.</p> <p><img style="max-width: 100%; width: auto; height: auto;" src="/link/3465e8f0b2034908a7db6ea1731dec62.aspx" alt="" width="2268" height="1288" /></p>
